Add to my tools

Automatically number the lines of a text in seconds. Paste your text and the tool adds a number in front of each line, which is handy for organising a list, preparing a document or structuring content.

Paste or type your text, choose the desired separator, then click "Number". Each line will be preceded by its number.

Number the lines of a text

What is automatic line numbering used for?

Line numbering is a simple but essential operation in many contexts. Whether you're working on a to-do list, a document outline, a script or simply structured text, adding a number in front of each line immediately improves readability and navigation.

Examples

Original text:

Go grocery shopping
Call the doctor
Pay the bills

Result with "Period" separator:

1. Go grocery shopping
2. Call the doctor
3. Pay the bills

Available separators

Common use cases

Tip: The tool automatically aligns numbers for lists of more than 9 lines (e.g. " 1.", " 10.", "100."), ensuring a clean rendering in a monospace font.
